SAFETY

GENERAL SAFETY RULES – FOR ALL BATTERY OPERATED TOOLS

WARNING: Read and understand all instructions.

Failure to follow all instructions listed below, may result in electric shock,

fire and/or serious personal injury.

SAVE THESE INSTRUCTIONS

1. Work Area

(1) Keep your work area clean and well lit. Cluttered benches and dark areas invite

accidents.

(2) Do not operate power tools in explosive atmospheres, such as in the presence of

flammable liquids, gases, or dust. Power tools create sparks which may ignite the

dust of fumes.

(3) Keep bystanders children, and visitors away while operating a power tool.

Distractions can cause you to lose control.

2. Electrical Safety

(1) A battery operated tool with integral batteries or a separate battery pack must be

recharged only with the specified charger for the battery.

A charger that may be suitable for one type of battery may create a risk of fire when

used with another battery.

(2) Use battery operated tool only with specifically designed battery pack.

Use of any other batteries may create a risk of fire.

3. Personal Safety

(1) Stay alert, watch what you are doing and use common sense when operating a

power tool. Do not use tool while tired or under the influence of drugs, alcohol, or

medication. A moment of inattention while operating power tools may result in

serious personal injury.

(2) Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your

hair, clothing and gloves away from moving parts. Loose clothes, jewelry, or long hair

can be caught in moving parts.

(3) Avoid accidental starting. Be sure switch is off position before inserting battery.

Carrying tools with your finger on the switch or inserting the battery pack into a tool

that have the switch on invites accidents.

(4) Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that

is left attached to a rotating part of the tool may result in personal injury.

(5) Do not overreach. Keep proper footing and balance at all times. Proper footing and

balance enable better control of the tool in unexpected situations.

(6) Use safety equipment. Always wear eye protection. Dust mask, non-skid safety

shoes, hard hat, or hearing protection must be used for appropriate conditions.

English

5

4. Tool Use and Care

(1) Use clamps or other practical way to secure and support the workpiece to a stable

platform. Holding the work by hand or against your body is unstable and may lead to

loss of control.

(2) Do not force tool. Use the correct tool for your application. The correct tool will do

the job better and safer at the rate for which it is designed.

(3) Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled

with the switch is dangerous and must be repaired.

(4) Disconnect battery pack from tool or place the switch in the locked or off position

before making any adjustments, changing accessories, or storing the toos. Such

preventive safety measures reduce the risk of starting the tool accidentally.

(5) Store idle tools out of reach of children and other untrained persons. Tools are

dangerous in the hands of untrained users.

(6) When battery pack is not in use, keep it away from other metal objects like: paper

clips, coins, keys, nails, screws, or other small metal objects that can make a

connection from one terminal to another.

Shorting the battery terminals together may cause sparks, burns, or a fire.

(7) Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained

tools, with sharp cutting edges are less likely to bind and are easier to control.

(8) Check for misalignment or binding of moving parts, breakage of parts, and any other

condition that may affect the tools operation. If damaged, have the tool serviced by

a HITACHI authorized service center before using. Many accidents are caused by

poorly maintained tools.

(9) Use only accessories that are recommended by the manufacturer for your model.

Accessories that may be suitable for one tool, may become hazardous when used on

another tool.

5. Service

(1) Tool service must be performed only by a HITACHI authorized service center. Service

or maintenance performed by unqualified personnel could result in a risk of injury.

(2) When servicing a tool, use only identical replacement parts. Follow instructions in

the Maintenance section of this manual. Use of unauthorized parts or failure to follow

Maintenance Instruction may create a risk of electric shock or injury.

WARNING:

Some dust created by power sanding, sawing, grinding, drilling, and other construction

activities contains chemicals known to the State of California to cause cancer, birth defects

or other reproductive harm. Some examples of these chemicals are:

● Lead from lead-based paints,

● Crystalline silica from bricks and cement and other masonry products, and

● Arsenic and chromium from chemically-treated lumber.

Your risk from these exposures varies, depending on how often you do this type of work.

To reduce your exposure to these chemicals: work in a well ventilated area, and work with

approved safety equipment, such as those dust masks that are specially designed to filter

out microscopic particles.

CAUTION:

Do not pull the plug out of the receptacle by pulling on the cord.

Make sure to grasp the plug when removing from receptacle to avoid damaging cord.

5. Remove the battery from the battery charger.

Supporting the battery charger with hand, pull out the battery from the battery charger.

CAUTION:

● When the battery charger has been continuosly used, the battery charger will be heated,

thus constituting the cause of the failures. Once the charging has been completed, wait

15 minutes rest until the next charging.

● If the battery is rechraged when it is warm due to battery use or exposure to sunlight,

the pilot lamp may not light.

The battery will not be recharged. In such a case, let the battery cool before charging.

Regarding electric discharge in case of new batteries, etc.

As the internal chemical substance of new batteries and batteries that have not been used

for an extended period is not activated, the electric discharge might be low when using

them the first and second time. This is a temporary phenomenon, and normal time

required for recharging will be restored by recharging the batteries 2 – 3 times.

How to make the batteries perform longer.

(1) Recharge the batteries before they become completely exhausted.

When you feel that the power of the tool becomes weaker, stop using the tool and

recharge its battery. If you continue to use the tool and exhaust the electric current, the

battery may be damaged and its life will become shorter.

(2) Avoid recharging at high temperatures.

A rechargeable battery will be hot immediately after use. If such a battery is recharged

immediately after use, its internal chemical substance will deteriorate, and the battery life

will be shortened. Leave the battery and recharge it after it has cooled for a while.

BEFORE USE

Check the work area to make sure that it is clear of debris and clutter.

Clear the area of unnecessary personnel. Ensure that lighting and ventilation is adequate.
